42×32×21=
To solve this problem, I will follow these clear steps:
- Step 1: Multiply the numerators of the fractions: 2×2×1.
- Step 2: Multiply the denominators of the fractions: 4×3×2.
- Step 3: Simplify the resulting fraction.
Let's work through each step:
Step 1: Multiply the numerators: 2×2×1=4.
Step 2: Multiply the denominators: 4×3×2=24.
Step 3: Combine these results to write the product as a fraction:
244.
We need to simplify this fraction:
Find the greatest common divisor (GCD) of 4 and 24, which is 4.
Divide both the numerator and the denominator by their GCD:
244=24÷44÷4=61.
Therefore, the solution to the problem is 61.
