Question

If a:b =5:6 and b:c=18:23 find a:b:c

Answer 1

Given that,

a:b = 5:6...(I)

b:c=18:23...(II)

We need to calculate the value of a:b:c

Using formula for a:b:c

$a:b:c=(a\times b):(b\times b):(b\times c)$

Put the value into the formula

$a:b:c=(5\times18):(6\times18):(6\times23)$

$a:b:c=90:108:138$

$a:b:c=15:18:23$

Hence, The value of a:b:c is 15:18:23

Answer 2

Answer:

a:b = 5:6...(I)

b:c=18:23...(II)

We need to calculate the value of a:b:c

Using formula for a:b:c

a:b:c=(a\times b):(b\times b):(b\times c)a:b:c=(a×b):(b×b):(b×c)

Put the value into the formula

a:b:c=(5\times18):(6\times18):(6\times23)a:b:c=(5×18):(6×18):(6×23)

a:b:c=90:108:138a:b:c=90:108:138

a:b:c=15:18:23a:b:c=15:18:23
