Answer:
10^4 or 10,000
Step-by-step explanation:
This is a division problem. Think of the problem with easy, small numbers.
If the problem were "20 is ? times as much as 10?", you'd do 20/10 = 2, and the answer is 2.
Now we do the same with the numbers of this problem.
"4x10^7 is ? Times as much as 4x10^3"
Do this division:
(4x10^7)/(4x10^3) = 4/4 * 10^(7 - 3) = 1 * 10^4 = 10,000
Answer: 10^4 or 10,000
4x10^7 =40000000
4x10^3=4000
It is 10,000 larger
jx(W)
y =84
25/100*Y = 21
100/25 * 25y/100 =21 *100/25
y = 2100/25
y = 84
