1 & 2/5 × 5
so simple, yet so wrong
1 2/5 = 7/5
7/5 * 5 = 7
Apologies for the mistake in the previous response.
You are correct. The mixed number 1 2/5 can be expressed as the improper fraction 7/5. Multiplying 7/5 by 5 gives:
(7/5) * 5 = (7 * 5) / 5 = 35/5 = 7.
Therefore, the correct answer is 7.
To calculate this expression, we first need to convert the mixed number 1 & 2/5 into an improper fraction.
1 & 2/5 can be expressed as (5 * 1) + 2/5 = 5 + 2/5 = 5 + 2/5.
Next, multiply the whole number by the denominator of the fraction and add the numerator. This gives us (5 * 5 + 2)/5 = (25 + 2)/5 = 27/5.
Finally, multiply the resulting fraction (27/5) by 5:
27/5 * 5 = (27 * 5)/(5 * 1) = 135/5 = 27.
Therefore, 1 & 2/5 × 5 equals 27.
