Answer:
The fraction will increase by 100%
Step-by-step explanation:
Say the fraction is x/y. The question is telling us to decrease x by 20% (i.e. 0.8x) and to decrease y by 60% (i.e. 0.4y):

You can see that by applying these changes, the new fraction is actually double the old fraction (i.e. will increase by 100%).
Answer:
41
Step-by-step explanation:
x² = 40²+9²

= 1681
x= √1681 = 41
You have to divide the numerator (top number) by the denominator (bottom number). For example, 1/2 is 0.5
However, some end up as never-ending decimals, like 1/3, which converts to 0.333 repeating.
