Answer:_______________




 

1)  

5 similar watches weigh 340 g more than 2 similar clocks.
If one watch weighs 170 g, how heavy is one clock

Answer: 255 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 170 g x 5 = 850 g
Step 2: Weight of 2 clocks → 850 g - 340 g = 510 g
Step 3: Weight of 1 clock → 510 g ÷ 2 = 255 g

One clock is 255 g.



2)  

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.



3)  

5 similar watches weigh 340 g more than 2 similar clocks.
If one watch weighs 100 g, how heavy is one clock

Answer: 80 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 100 g x 5 = 500 g
Step 2: Weight of 2 clocks → 500 g - 340 g = 160 g
Step 3: Weight of 1 clock → 160 g ÷ 2 = 80 g

One clock is 80 g.



4)  

5 similar watches weigh 370 g more than 2 similar clocks.
If one watch weighs 100 g, how heavy is one clock

Answer: 65 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 100 g x 5 = 500 g
Step 2: Weight of 2 clocks → 500 g - 370 g = 130 g
Step 3: Weight of 1 clock → 130 g ÷ 2 = 65 g

One clock is 65 g.



5)  

5 similar watches weigh 330 g more than 2 similar clocks.
If one watch weighs 220 g, how heavy is one clock

Answer: 385 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 220 g x 5 = 1100 g
Step 2: Weight of 2 clocks → 1100 g - 330 g = 770 g
Step 3: Weight of 1 clock → 770 g ÷ 2 = 385 g

One clock is 385 g.



6)  

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.



7)  

5 similar watches weigh 250 g more than 2 similar clocks.
If one watch weighs 230 g, how heavy is one clock

Answer: 450 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 230 g x 5 = 1150 g
Step 2: Weight of 2 clocks → 1150 g - 250 g = 900 g
Step 3: Weight of 1 clock → 900 g ÷ 2 = 450 g

One clock is 450 g.



8)  

5 similar watches weigh 260 g more than 2 similar clocks.
If one watch weighs 150 g, how heavy is one clock

Answer: 245 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 150 g x 5 = 750 g
Step 2: Weight of 2 clocks → 750 g - 260 g = 490 g
Step 3: Weight of 1 clock → 490 g ÷ 2 = 245 g

One clock is 245 g.



9)  

5 similar watches weigh 370 g more than 2 similar clocks.
If one watch weighs 120 g, how heavy is one clock

Answer: 115 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 120 g x 5 = 600 g
Step 2: Weight of 2 clocks → 600 g - 370 g = 230 g
Step 3: Weight of 1 clock → 230 g ÷ 2 = 115 g

One clock is 115 g.



10)  

5 similar watches weigh 380 g more than 2 similar clocks.
If one watch weighs 210 g, how heavy is one clock

Answer: 335 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 210 g x 5 = 1050 g
Step 2: Weight of 2 clocks → 1050 g - 380 g = 670 g
Step 3: Weight of 1 clock → 670 g ÷ 2 = 335 g

One clock is 335 g.
