Simplify the following fraction multiplications: 12×67\frac{1}{2} \times \frac{6}{7} and 56×39\frac{5}{6} \times \frac{3}{9}.

STEP 1

Assumptions
1. We are performing multiplication of two fractions in each part of the problem.
2. To multiply two fractions, we multiply the numerators together and the denominators together.

STEP 2

Let's solve part (a) of the problem. Multiply the numerators of the two fractions.
12×67=1×62×7\frac{1}{2} \times \frac{6}{7} = \frac{1 \times 6}{2 \times 7}

STEP 3

Now, multiply the denominators of the two fractions.
1×62×7=614\frac{1 \times 6}{2 \times 7} = \frac{6}{14}

STEP 4

Simplify the fraction if possible. In this case, both the numerator and the denominator are divisible by 2.
614=6÷214÷2\frac{6}{14} = \frac{6 \div 2}{14 \div 2}

STEP 5

Perform the division to simplify the fraction.
6÷214÷2=37\frac{6 \div 2}{14 \div 2} = \frac{3}{7}

STEP 6

The solution for part (a) is 37\frac{3}{7}.

STEP 7

Now, let's solve part (b) of the problem. Multiply the numerators of the two fractions.
56×39=5×36×9\frac{5}{6} \times \frac{3}{9} = \frac{5 \times 3}{6 \times 9}

STEP 8

Now, multiply the denominators of the two fractions.
5×36×9=1554\frac{5 \times 3}{6 \times 9} = \frac{15}{54}

STEP 9

Simplify the fraction if possible. In this case, both the numerator and the denominator are divisible by 3.
1554=15÷354÷3\frac{15}{54} = \frac{15 \div 3}{54 \div 3}

STEP 10

Perform the division to simplify the fraction.
15÷354÷3=518\frac{15 \div 3}{54 \div 3} = \frac{5}{18}

STEP 11

The solution for part (b) is 518\frac{5}{18}.
The solutions are: a. 37\frac{3}{7} b. 518\frac{5}{18}
