30% of 90 whenever it says "of" put in a multiplication sign

30% x 90 take out the % sign (percent means divided by 100)

30/100 = 3/10 simplify, then multiply by 90

3/10 x 90 = 270/10 simplify

270 = 27

90 - 27 = 63 subtract 27 because it is the amount read so far from the total

Keisha has to read 63 more minutes to reach her goal.
