Answer:
A. ¹/₁₄ lb
Step-by-step explanation:
¹/₁₆ lb sand goes with ⅞ lb compost.
For 1 lb compost, the mass of sand needed is:
1 lb compost × (¹/₁₆ lb sand)/(⅞ lb compost).
We must evaluate the fraction (¹/₁₆)/(⅞).
Invert the denominator and multiply
(¹/₁₆)/(⅞) = ¹/₁₆ × ⁸/₇ Cancel the 8s
= ½ × ⅐ Multiply numerators and denominators
= ¹/₁₄
For 1 lb of compost, the mass of sand needed is ¹/₁₄ lb.
29 = 13 + 4x
16 = 4x
x = 4
The number is 4
