The <em>correct answer</em> is:
3 1/2.
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
Answer:
Step-by-step explanation:
- Mother's age = m
- Son's age = s
<u>3 years later:</u>
- m + 3 = 4(s + 3) ⇒ m = 4s + 12 - 3 = 4s + 9
<u>3 years ago:</u>
- m - 3 = 2(s + 8) ⇒ m = 2s + 18 + 3 = 2s + 21
<u>Solve for s by substitution:</u>
- 4s + 9 = 2s + 21
- 2s = 12
- s = 6
<u>Find the value of m:</u>
Mother is 33 and son is 6
