Question

1 1/4×-1 1/3 is equals to?​

Answer 1

Answer: $-\frac{5}{12}$

Steps:

$1\frac{1}{4}\times \left(-1\right)\frac{1}{3}$

Convert mixed numbers to improper fractions: $1\frac{1}{4}$$=\frac{5}{4}$

$=\frac{5}{4}\times \left(-1\right)\frac{1}{3}$

$\mathrm{Apply\:the\:rule}:\quad \:a\left(-b\right)=-ab$

$\frac{5}{4}\left(-1\right)=-\frac{5}{4}\times \:1$

$=-\frac{5}{4}\times \:1\times \frac{1}{3}$

$\mathrm{Apply\:rule}\:a\times 1=a$

$=-\frac{5}{4}\times \frac{1}{3}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}$

$\frac{5}{4}\times \frac{1}{3}=\frac{5\times \:1}{4\times \:3}$

$=-\frac{5\times \:1}{4\times \:3}$

$\mathrm{Multiply\:the\:numbers:}\:5\times \:1=5$

$=-\frac{5}{4\times \:3}$

$\mathrm{Multiply\:the\:numbers:}\:4\times \:3=12$

$=-\frac{5}{12}$

Hope This Helps!
