To answer this, it's best to first convert both numbers into improper fractions. That's done by multiplying the whole part of the mixed number by the denominator, and adding it to the numerator.
In this case, 4 and 1/4 will become 17/4
7 and 2/5 will become 37/5
The next step is to multiply numerators and denominators.
17x37 = 629
4x5 = 20
That can then be converted back into the mixed number 31 and 9/20
1/4 times 2 is 1/2
1/2 *1/4= 1/8
1/4
2/4 = 1/2
5/3 x 4/5 x 3/2 = 60/30 = 2
It is 6 times 1/4 = 1 and 1/2 or 1.5
1 1/2 x 3/4 is 1 1/8
its easy its 1 and 4 over 7
2/5
1/4
2 over 8 because 1 over 4 times 2 is 2 over 8
4 1/2 x 53 1/3 = 240
