1 4/8 in a improper fraction?

stiv31 [10]

<h2>Answer: $\frac{3}{2}$ <u><em></em></u></h2>

Step-by-step explanation:

Step 1: Multiply the whole number part (1) by the denominator (8).

1 × 8 = 8

Step 2: Add the product from Step 1 (8) to the numerator (4).

8 + 4 = 12

Step 3: Write that result (12) above the denominator. So,

$\frac4{8}{1}$

Step 4: The fraction $\frac{12}{8}$

Can be reduced by dividing both numerator and denominator by the GCD(12,8) = 4. Thus,

$\frac1{4}{8} =\frac{3}{2}$
