Answer:_______________




 

1)  

5 similar watches weigh 260 g more than 2 similar clocks.
If one watch weighs 200 g, how heavy is one clock

Answer: 370 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 200 g x 5 = 1000 g
Step 2: Weight of 2 clocks → 1000 g - 260 g = 740 g
Step 3: Weight of 1 clock → 740 g ÷ 2 = 370 g

One clock is 370 g.



2)  

5 similar watches weigh 270 g more than 2 similar clocks.
If one watch weighs 200 g, how heavy is one clock

Answer: 365 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 200 g x 5 = 1000 g
Step 2: Weight of 2 clocks → 1000 g - 270 g = 730 g
Step 3: Weight of 1 clock → 730 g ÷ 2 = 365 g

One clock is 365 g.



3)  

5 similar watches weigh 310 g more than 2 similar clocks.
If one watch weighs 190 g, how heavy is one clock

Answer: 320 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 190 g x 5 = 950 g
Step 2: Weight of 2 clocks → 950 g - 310 g = 640 g
Step 3: Weight of 1 clock → 640 g ÷ 2 = 320 g

One clock is 320 g.



4)  

5 similar watches weigh 270 g more than 2 similar clocks.
If one watch weighs 120 g, how heavy is one clock

Answer: 165 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 120 g x 5 = 600 g
Step 2: Weight of 2 clocks → 600 g - 270 g = 330 g
Step 3: Weight of 1 clock → 330 g ÷ 2 = 165 g

One clock is 165 g.



5)  

5 similar watches weigh 400 g more than 2 similar clocks.
If one watch weighs 140 g, how heavy is one clock

Answer: 150 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 140 g x 5 = 700 g
Step 2: Weight of 2 clocks → 700 g - 400 g = 300 g
Step 3: Weight of 1 clock → 300 g ÷ 2 = 150 g

One clock is 150 g.



6)  

5 similar watches weigh 260 g more than 2 similar clocks.
If one watch weighs 180 g, how heavy is one clock

Answer: 320 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 180 g x 5 = 900 g
Step 2: Weight of 2 clocks → 900 g - 260 g = 640 g
Step 3: Weight of 1 clock → 640 g ÷ 2 = 320 g

One clock is 320 g.



7)  

5 similar watches weigh 310 g more than 2 similar clocks.
If one watch weighs 150 g, how heavy is one clock

Answer: 220 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 150 g x 5 = 750 g
Step 2: Weight of 2 clocks → 750 g - 310 g = 440 g
Step 3: Weight of 1 clock → 440 g ÷ 2 = 220 g

One clock is 220 g.



8)  

5 similar watches weigh 310 g more than 2 similar clocks.
If one watch weighs 220 g, how heavy is one clock

Answer: 395 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 220 g x 5 = 1100 g
Step 2: Weight of 2 clocks → 1100 g - 310 g = 790 g
Step 3: Weight of 1 clock → 790 g ÷ 2 = 395 g

One clock is 395 g.



9)  

5 similar watches weigh 330 g more than 2 similar clocks.
If one watch weighs 120 g, how heavy is one clock

Answer: 135 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 120 g x 5 = 600 g
Step 2: Weight of 2 clocks → 600 g - 330 g = 270 g
Step 3: Weight of 1 clock → 270 g ÷ 2 = 135 g

One clock is 135 g.



10)  

5 similar watches weigh 320 g more than 2 similar clocks.
If one watch weighs 220 g, how heavy is one clock

Answer: 390 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 220 g x 5 = 1100 g
Step 2: Weight of 2 clocks → 1100 g - 320 g = 780 g
Step 3: Weight of 1 clock → 780 g ÷ 2 = 390 g

One clock is 390 g.
