Answer 3

1)

15 x 70%

= 15 x 70/100

= 15 x 7/10

= 105/10

= 10.5

2)

200 x 35%

= 200 x 35/100

= 200 x 7/20

= 1400/20

= 70

Answer 4

0.7 x 15 = 10.5

For 35% of 200, u can just find 35% of 100, which is 35 and double it, which is 70.

Answer 5

When it asks for a percentage, take the percentage number (ex, 70%) and just put a decimal before the tenth place (in this case, before the 7 [now it's 0.70]) and then multiply it by 15. So 0.70 x 15 = 10.5. Now, do the same for the other.

Answer 6

70/100 x 15 = 21/2 = 10.5

35/100 x 200 = 35 x 2 = 70

Answer 7

10 % of 15 is  1.5 multiply by 7 to get 70% so 1.5 * 7 = 10.5

10 % of 200 is 20 multiply by 3.5 to get 35% so 20 * 3.5 = 70

So 70 % of 15 is 10.5

and 35 % of 200 is 70

Hope that helps !!!

Answer 10

hi sissy;

to know answer for such a questions u need to multiply the quantity by the percentage in its decimal form ( i.e. 19% becomes 1/100; 70% becomes 70/100). therefore  

70% of 15 is 15 * (70/100) = 15*7/10 = 105/10 = 10.5

35% of 200 is 200*(35/100) = 2*(35/1) = 70
