Keisha wants to meet for 90 minutes so far she has read 30% of her goal how much longer does she need to read to reach her goal
sladkih [1.3K]

Answer:

30% of 90             

30% x 90              

30/100 =3/10              

3/10 x 90 = 270/10          

270 = 27     

90 - 27 = 63          

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