It can be helpful to rearrange numerators and denominators so you can see the factors cancel. The result is negative if the number of negative factors is odd. Mixed numbers are often easier to multiply if changed to improper fractions first.
- (5/16)(-2)(-4)(-4/5) = -(5/5·(4·4)/16·2) = -2
- (2/3)(-4)(9) = -(9/3·2·4) = -24
- (2 3/5)(7/9) = 13/5·7/9 = (13·7)/(5·9) = 91/45
- (-3/4)(7/8) = -(3·7)/(4·8) = -21/32
An irrational number is a number which cannot be expressed in a ratio of two integers. In rational numbers, both numerator and denominator are whole numbers, where the denominator is not equal to zero. While an irrational number cannot be written in a fraction.
