Answer 1

Answer:

a) 7/10-3/25

35-6/25

29/25

Answer 2

$( \frac{ - 8}{13}) \times ( \frac{ - 3}{26} )$

Multiply and reduce

$\frac{ \not{8}}{13} \times \frac{3}{ \not{26}} = \frac{4}{13} \times \frac{3}{13}$

$\frac{4}{13} \times \frac{3}{13}$

multiply it

$\frac{12}{169}$

solution

$\boxed{ \frac{12}{169 } }$

alternate form

$≈0.0710059$
