Question

What shuld be added to 6 whole 3/4 to get 9?

Answer 1

Answer:

Let the number should be added to

$6 \frac{3}{4}$

be 'x'

Now

we will get a equation

$6 \frac{3}{4} + x = 9$

Convert the given mixed fraction into improper fraction

$6 \frac{3}{4} = \frac{4 \times 6 + 3}{4} \\ \\ \: \: \: \: \: \: \: \: \: = \frac{27}{4}$

now,

substitute

$\frac{27}{4} + x = 9 \\ \\ x = 9 - \frac{27}{4}$

$x = \frac{36 - 27}{4}$

$x = \frac{9}{4}$

for verification

Let's substitute the value of x for verification

$\frac{27}{4} + \frac{9}{4} \\ \\ \frac{36}{4} = 4$

LHS = RHS
