How do you solve \(\frac{4a}{b} \div \frac{2ac}{b}\)?
Answer (3)
b 4 a : b 2 a c = b 4 a ⋅ 2 a c b = c 2 a an d c = 0
b 2 a c b 4 a = ? T o d i v i d e f r a c t i o n m u lt i pl y f i rs t f r a c t i o n b y in v erse o f t h e seco n d : b 2 a c b 4 a = b 4 a ∗ 2 a c b = ? S h or t e nin g f r a c t i o n s : b 2 a c b 4 a = b 4 a ∗ 2 a c b = c 2 S o l u t i o n i s c 2 .
To solve b 4 a ÷ b 2 a c , convert the division to multiplication by the reciprocal. This simplifies to c 2 , provided that a and c are not zero.
