Multiply. Simplify if you can.
2.1/3x2/5=2/15
4.2/5x3/7=6/35
6.1/6x3/5=3/30
8.9/10x4/5=36/50
10.11x3/4=33/4=8 1/4
12.4/9x2/3=8/27
6 and 8 can be simplified
The others are correct.
6 is 1/10 8 is 18/25
Right.
To simplify the multiplication of fractions, follow these steps:
1. Multiply the numerators (the numbers on top) together.
2. Multiply the denominators (the numbers on the bottom) together.
3. Write the product of the numerators over the product of the denominators.
Let's go through each example to demonstrate:
1. 2.1/3 * 2/5 =
Multiply the numerators: 2.1 * 2 = 4.2
Multiply the denominators: 3 * 5 = 15
Simplify: 4.2/15
2. 4.2/5 * 3/7 =
Multiply the numerators: 4.2 * 3 = 12.6
Multiply the denominators: 5 * 7 = 35
Simplify: 12.6/35 or 6/35
3. 6.1/6 * 3/5 =
Multiply the numerators: 6.1 * 3 = 18.3
Multiply the denominators: 6 * 5 = 30
Simplify: 18.3/30 or 3/30
4. 8.9/10 * 4/5 =
Multiply the numerators: 8.9 * 4 = 35.6
Multiply the denominators: 10 * 5 = 50
Simplify: 35.6/50 or 36/50
5. 10.11 * 3/4 =
Multiply the whole number (10) by the denominator (4) and add the product to the numerator (11): (10 * 4) + 11 = 51
Simplify: 51/4 or 12 3/4
6. 4/9 * 2/3 =
Multiply the numerators: 4 * 2 = 8
Multiply the denominators: 9 * 3 = 27
Simplify: 8/27
Remember to always simplify the fraction, if possible, by dividing the numerator and denominator by their greatest common divisor.
