Question

Find 1 1/10(−6 7/8) . Write your answer as a mixed number in simplest form.

Answer 1

Answer:

$-5\dfrac{31}{40}$

Step-by-step explanation:

Convert to improper fractions:

$1\dfrac{1}{10}-6\dfrac78=\dfrac{1 \times10+1}{10}-\dfrac{6 \times8+7}{8}=\dfrac{11}{10}-\dfrac{55}{8}$

Make denominators the same:

$\dfrac{11}{10}-\dfrac{55}{8}=\dfrac{11\times8}{10\times8}-\dfrac{55\times10}{8\times10}=\dfrac{88}{80}-\dfrac{550}{80}$

Therefore,

$\dfrac{88}{80}-\dfrac{550}{80}=\dfrac{88-550}{80}=-\dfrac{462}{80}=-\dfrac{231}{40}$

Convert to mixed number:

$-\dfrac{231}{40}=-5\dfrac{31}{40}$
