We've already learnt how to add, subtract, multiply and divide fractions. Similarly, we've looked at each of these operations with negative numbers.
The process is just the same when we have questions with negatives fractions. We saw this in The More or Less of Plus and Minus when we learnt how to add and subtract negative fractions.
Calculate: $3+4-\frac{-4}{5}$3+4−−45.
Think: Following the order of operations, we will solve the addition and subtraction, working from left to right.
Do:
$3+4-\frac{-4}{5}$3+4−−45 | $=$= | $7-\frac{-4}{5}$7−−45 |
$=$= | $7+\frac{4}{5}$7+45 | |
$=$= | $7\frac{4}{5}$745 |
Evaluate $4\times\left(\frac{5}{9}-\frac{5}{6}\right)$4×(59−56), writing your answer in its simplest form.
So we can write our final answer as $\frac{-10}{9}$−109 or $-1\frac{1}{9}$−119.
Evaluate $1\frac{8}{9}\times\left(-3\frac{1}{5}\right)\div\frac{8}{11}$189×(−315)÷811
Calculate $3+4-\left(-\frac{4}{5}\right)$3+4−(−45).
