Answer:
x= 50
Step-by-step explanation:
7/x = 14/100
14x = 700
x = 50
the reason behind my calculations were to get the same ratios and because they gave us percentage and the actual number, we can set them; 14 percent 14/100, however, the 7/x is because we don't know the 100 percent of the coins which is what we look for. Therefore, you cross multiply and get x.

Answer:
2.) 2703
4.) 9
Step-by-step explanation:
2.)
5327 - 2624 = ?
We subtract from left to right to get;
(7 - 4 = 3) then (2 - 2 = 0) then carrying 1 from 5, (13 - 6 = 7) and (4 - 2 = 2)
So writing the answer;
2 then 7 then 0 then 3
i.e Answer = 2703
4.)
648 ÷ 72 = ?
72 × 10 = 720
So we must multiply 72 by a number less than 10 since 720 > 648
We should look for a number such that 2 in 72 times the number should give an answer with 8 in the end.
Such a number can be 9;
Manually multiplying 72 and 9 we get 648 and we are right!
