The correct answer is:
3 1/2.
Step-by-step explanation:
To find out how many 1/4 tsp doses are in 7/8 tsp of medicine, we divide:
7/8 ÷ 1/4
To divide fractions, flip the second fraction and multiply:
7/8 × 4/1
Multiply straight across:
7/8 × 4/1 = (7×4)/(8×1) = 28/8
To simplify this, we see how many times 8 will divide into 28. It divides evenly 3 times; this is our whole number.
After 8 goes into 28 3 times, there are 4 left over. This is the numerator of our fraction (8 is the denominator):
3 4/8 = 3 1/2
