Multiply. Simplify and write the answer as a mixed number.
4*3/7
A) 5 1/7
B) 12/7
C) 3/28
D) 1 5/7
To multiply 4 by 3/7, we can multiply the numerators and multiply the denominators:
4 * 3 = 12
7
So the answer is 12/7. However, since we are asked to write the answer as a mixed number, we need to convert the improper fraction 12/7 into a mixed number.
To do this, we divide the numerator (12) by the denominator (7):
12 ÷ 7 = 1 remainder 5
The whole number part of the mixed number is the quotient of the division, which is 1. The fractional part is the remainder (5) over the original denominator (7).
So the final answer as a mixed number is 1 5/7.
Therefore, the correct option is:
D) 1 5/7
