Question

Find the value of n in the following
A.3/4=23/n
B.28/56=4/n
C.20/45=n/9

Answer 1

Find the value of n in the following

A.3/4=23/n

B.28/56=4/n

C.20/45=n/9

Answer 2

$\large\sf\underline{Question\:A}$

$\sf\:\frac{3}{4}=\frac{23}{n}$

$\sf➞\:3n=23 \times 4$

$\sf➞\:3n=92$

$\sf➞\:n=\frac{92}{3}$

$\small{\underline{\boxed{\mathrm\pink{➞\:n=30.66}}}}$

$\large\sf\underline{Question\:B}$

$\sf\:\frac{28}{56}=\frac{4}{n}$

$\sf➞\:28n=4 \times 56$

$\sf➞\:28n=224$

$\sf➞\:n=\frac{224}{28}$

$\small{\underline{\boxed{\mathrm\pink{➞\:n=8}}}}$

$\large\sf\underline{Question\:C}$

$\sf\:\frac{20}{45}=\frac{n}{9}$

$\sf➞\:45n=9 \times 20$

$\sf➞\:45n=180$

$\sf➞\:n=\frac{180}{45}$

$\small{\underline{\boxed{\mathrm\pink{➞\:n=4}}}}$
