Answer:
Step-by-step explanation:
x1 / y1 times x2 / y2 where are two fractions
x1/y1 times x2/y2 = x1 times x2 / y1 times y2 = z1 / z2 z is a new fraction
fractions multiply like regular wholes number, which can also be represented in fractional form
Examples:
2/1 times 3/1 = 2x3 /1x1 6/1
10/2 x 18/3 = 180/6 now look at 10/2 = 5 18/3 = 6 5x6 = 30
5 x 6 = 30
Now apply to your fractions:
3/7 x 4/5 = 3x4 / 7x5
12/35
