32×43=
To solve this problem, follow these steps:
- Step 1: Multiply the numerators of the fractions. The numerators are 2 and 3.
- Step 2: Multiply the denominators of the fractions. The denominators are 3 and 4.
- Step 3: Simplify the resulting fraction if necessary.
Now, let us perform the multiplication:
Step 1: Multiply the numerators:
2×3=6
Step 2: Multiply the denominators:
3×4=12
So, the product of the fractions is:
126
Step 3: Simplify the fraction. To simplify, find the greatest common divisor (GCD) of 6 and 12, which is 6. Divide both numerator and denominator by 6:
12÷66÷6=21
Therefore, the simplified product of the fractions 32×43 is 21.
This matches choice 4, which is 21.
