Question

Use given tape diagram to to find the value to be filled
A : B = 30 :

Answer 1

From the tape diagram we can see
A:B = 5:4

Also,
$\frac{\text{A}}{\text{B}}=\frac{5}{4}$
$\frac{5}{4}=\frac{5\times 6}{4\times 6}$ $\text{(multiplying by 6 to get 30 as antecedent )}$
$=\frac{30}{24}$
Hence the value would be 24.
