I like to do these equations backwards and multiply the first number by the opposite of it. ( think 1- the percent as a decimal) however, you can do this by converting the percent into a decimal and then subtracting that from the original number.
Have a great day!
For the first one (aka 7) you would write 10² wich is the same as 10×10 and so the answer is 100
For the second one (aka 8) you would write 3×3×3×3×3×3×3×3×3 and the answer is 486 square miles
Answer:
1. 57 2. 81
Step-by-step explanation:
71x2=142 256-142=114/2= 57
5103/63= 81
Yes because if you divide both, the numerator and denominator, by 7 it would simplify to 10/3, so they are equivalent.
