Question

How can you add, subtract and multiply with decimals

Answer 1

Lets Take two decimals 1.01 and 2.32

Addition:-

$\\ \sf\longmapsto 1.01+2.32$

$\\ \sf\longmapsto \dfrac{101}{100}+\dfrac{232}{100}$

$\\ \sf\longmapsto \dfrac{333}{100}$

$\\ \sf\longmapsto 3.33$

Subtraction:-

$\\ \sf\longmapsto 2.32-1.01$

$\\ \sf\longmapsto \dfrac{232}{100}-\dfrac{101}{100}$

$\\ \sf\longmapsto \dfrac{131}{100}$

$\\ \sf\longmapsto 1.31$

Multiplication:-

$\\ \sf\longmapsto 1.01\times 2.32$

$\\ \sf\longmapsto \dfrac{101}{100}\times \dfrac{232}{100}$

$\\ \sf\longmapsto \dfrac{23432}{10000}$

$\\ \sf\longmapsto 2.3432$
