Question

A,24/100+0,27+13/100+36%                 B,7,15:0,5+7,15x9-7,15

Answer 1

a) \(\dfrac{24}{100}+0,27+\dfrac{13}{100}+36\%+\dfrac{24}{100}+\dfrac{27}{100}+\dfrac{13}{100}+\dfrac{36}{100}=\dfrac{24+27+13+36}{100}=\dfrac{100}{100}=1\)

b)\(7,15:0,5+7,15\times9-7,15\)

 \(=7,15:0,5+7,15\times9-7,15\times1\)

\(=7,15\times2+7,15\times9-7,15\times1\)

\(=7,15\times\left(2+9-1\right)\)

`=7,15xx10`

`=71,5`
