Solve the exercise using the substitutive property:
42×32×42=
To solve this problem, we need to multiply the three given fractions:
42×32×42
The steps involved in multiplying these fractions are as follows:
- Step 1: Multiply the numerators. The numerators are 2, 2, and 2. Multiplying these together gives:
2×2×2=8.
- Step 2: Multiply the denominators. The denominators are 4, 3, and 4. Multiplying these together gives:
4×3×4=48.
- Step 3: Combine the results to form a new fraction:
488.
- Step 4: Simplify the fraction. To simplify 488, we find the greatest common divisor (GCD) of 8 and 48, which is 8. Divide both the numerator and denominator by 8:
48÷88÷8=61.
Therefore, the solution to the given exercise is 61.
