1. (77+x)/2=84

2. Harold needs at least a 91

Work:

first, you multiply both sides by 2; 77+x=168
then you subtract 77 from both sides; x=91
then you plug it back in to check; (77+91)/2=84 ; 168/2=84 ; 84=84

By what percent will a fraction increase if its numerator is increased by 60% and its denominator is decreased by 20%?

Strike441 [17]

Lets just use $\frac{10}{20}$ for an example. If the number is increased by 60% and the denominator is decreased by 20% we get the new fraction being: $\frac{16}{16}$ . Since then new one is equal to 1, and the original is equal to $\frac{1}{2}$ , we see that this manipulation of the fraction causes an increase of 100%.
