Answer:
28/32 and 26/32
Step-by-step explanation:
A common denominator of 8 and 16 is 32.
7/8 = (7 * 4)/(8 * 4) = 28/32
13/16 = (13 * 2)/(16 * 2) = 26/32
Two equivalent fractions with a common denominator are 28/32 and 26/32.
Since b is a variable ( unknown) we replace b with 8 since its given to us so the equation turns to 8-3-3 which we do 8-3=5-3=2
2/3 x 3/4 =6/12=1/2
