Question

1)2 7/16 *8 2)4 3/4*6 1/3

Answer 1

Пошаговое объяснение:

$2 \frac{7}{16} \times 8 = \frac{39 \times 8}{16} = \frac{39}{2} = 19 \frac{1}{2} \\ \\ 4 \frac{3}{4} \times 6 \frac{1}{3} = \frac{19}{4} \times \frac{19}{3} = \frac{361}{12} = 30 \frac{1}{12}$

Answer 3

To multiply mixed numbers, you first need to convert them to improper fractions, then multiply the numerators and denominators. Here are the solutions to the two multiplication problems you provided:

1. 2 7/16 * 8:

Step 1: Convert the mixed number to an improper fraction. 2 7/16 can be written as (2 * 16 + 7)/16 = 39/16.

Step 2: Multiply the numerators and denominators. (39/16) * 8 = (39 * 8)/(16 * 1) = 312/16.

Step 3: Simplify the fraction if possible. The fraction 312/16 can be simplified by dividing both the numerator and denominator by their greatest common divisor (GCD), which is 8. 312/16 = (312/8) / (16/8) = 39/2.

So, 2 7/16 multiplied by 8 is equal to 39/2.

2. 4 3/4 * 6 1/3:

Step 1: Convert the mixed numbers to improper fractions. 4 3/4 = (4 * 4 + 3)/4 = 19/4. 6 1/3 = (6 * 3 + 1)/3 = 19/3.

Step 2: Multiply the numerators and denominators. (19/4) * (19/3) = (19 * 19)/(4 * 3) = 361/12.

Step 3: Simplify the fraction if possible. The fraction 361/12 cannot be simplified any further.

So, 4 3/4 multiplied by 6 1/3 is equal to 361/12.
