g


Answer:_______________




 

1)  

5 similar watches weigh 320 g more than 2 similar clocks.
If one watch weighs 170 g, how heavy is one clock

Answer: 265 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 170 g x 5 = 850 g
Step 2: Weight of 2 clocks → 850 g - 320 g = 530 g
Step 3: Weight of 1 clock → 530 g ÷ 2 = 265 g

One clock is 265 g.



2)  

5 similar watches weigh 250 g more than 2 similar clocks.
If one watch weighs 190 g, how heavy is one clock

Answer: 350 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 190 g x 5 = 950 g
Step 2: Weight of 2 clocks → 950 g - 250 g = 700 g
Step 3: Weight of 1 clock → 700 g ÷ 2 = 350 g

One clock is 350 g.



3)  

5 similar watches weigh 260 g more than 2 similar clocks.
If one watch weighs 170 g, how heavy is one clock

Answer: 295 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 170 g x 5 = 850 g
Step 2: Weight of 2 clocks → 850 g - 260 g = 590 g
Step 3: Weight of 1 clock → 590 g ÷ 2 = 295 g

One clock is 295 g.



4)  

5 similar watches weigh 390 g more than 2 similar clocks.
If one watch weighs 200 g, how heavy is one clock

Answer: 305 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 200 g x 5 = 1000 g
Step 2: Weight of 2 clocks → 1000 g - 390 g = 610 g
Step 3: Weight of 1 clock → 610 g ÷ 2 = 305 g

One clock is 305 g.



5)  

5 similar watches weigh 270 g more than 2 similar clocks.
If one watch weighs 160 g, how heavy is one clock

Answer: 265 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 160 g x 5 = 800 g
Step 2: Weight of 2 clocks → 800 g - 270 g = 530 g
Step 3: Weight of 1 clock → 530 g ÷ 2 = 265 g

One clock is 265 g.



6)  

5 similar watches weigh 290 g more than 2 similar clocks.
If one watch weighs 130 g, how heavy is one clock

Answer: 180 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 130 g x 5 = 650 g
Step 2: Weight of 2 clocks → 650 g - 290 g = 360 g
Step 3: Weight of 1 clock → 360 g ÷ 2 = 180 g

One clock is 180 g.



7)  

5 similar watches weigh 270 g more than 2 similar clocks.
If one watch weighs 130 g, how heavy is one clock

Answer: 190 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 130 g x 5 = 650 g
Step 2: Weight of 2 clocks → 650 g - 270 g = 380 g
Step 3: Weight of 1 clock → 380 g ÷ 2 = 190 g

One clock is 190 g.



8)  

5 similar watches weigh 270 g more than 2 similar clocks.
If one watch weighs 170 g, how heavy is one clock

Answer: 290 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 170 g x 5 = 850 g
Step 2: Weight of 2 clocks → 850 g - 270 g = 580 g
Step 3: Weight of 1 clock → 580 g ÷ 2 = 290 g

One clock is 290 g.



9)  

5 similar watches weigh 320 g more than 2 similar clocks.
If one watch weighs 130 g, how heavy is one clock

Answer: 165 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 130 g x 5 = 650 g
Step 2: Weight of 2 clocks → 650 g - 320 g = 330 g
Step 3: Weight of 1 clock → 330 g ÷ 2 = 165 g

One clock is 165 g.



10)  

5 similar watches weigh 280 g more than 2 similar clocks.
If one watch weighs 190 g, how heavy is one clock

Answer: 335 g


SOLUTION 1 :

Step 1: Weight of 5 watches → 190 g x 5 = 950 g
Step 2: Weight of 2 clocks → 950 g - 280 g = 670 g
Step 3: Weight of 1 clock → 670 g ÷ 2 = 335 g

One clock is 335 g.
