Ответ:
The answer is 2 hours.
Step-by-step explanation:
Let's use the Rule of Three Simple, this way:
Pages Time in hours
4/3 1/4
32/3 x
Solving for x, we have:
x * 4/3 = 32/3 * 1/4
4x/3 = 32/12
16x = 32 (Multiplying by 12 at both sides)
x = 32/16
x = 2 hours
Ответ:
Length of each smaller piece = 1/10 m
Number of pieces = n
n = 3/4 ÷ 1/10 ← Equation to solve n
n = 3/4 x 10/1
n = 30/4
n = 7 2/4
n = 7 1/2
7 pieces can be cut form the 3/4 m long wood.
