Question

4 9/20 + 7/12 - 1 13/15 simplify​

Answer 1

${ \underline{ \mathbf{ \blue{Given: }}}}$

$\: \: \:$

• $4 \dfrac{9}{20} + \dfrac{7}{12} + 1 \dfrac{13}{15}$

$\: \: \:$

${ \underline{ \mathbf{ \blue{To find: }}}}$

• The simplified answer

$\: \: \:$

${ \underbrace{ \mathbf{ \blue{Solution : }}}}$

$\: \: \:$

$4 \dfrac{9}{20} + \dfrac{7}{12} - 1 \dfrac{13}{15}$

$\: \: \:$

Note:-

Now make the mixed number into improper fraction by multiplying the denominator and the whole number. Than add the numerator by the product.

$\: \: \:$

$\dfrac{89}{20} + \dfrac{7}{12} - \dfrac{28}{15}$

$\: \: \:$

L.C.M of 20,12 and 15 is 3×4×5 = 60

$\: \: \:$

$\dfrac{267 + 35 + 112}{60}$

$\: \: \:$

$\dfrac{302 - 112}{60}$

$\: \: \:$

$\dfrac{190}{60}$

$\: \: \:$

Into mixed number:-

$\: \: \:$

$3 \dfrac{10}{60}$

$\: \: \:$

Verification:-

Multiply 60 and 3 than add 10

» 60×3+10

»180+10

»190

$\: \: \:$

Hence,

The simplified answer is $3 \dfrac{10}{60}$
