The figures below are similar. What is v?

mafiozo [28]

Answer:

v = 16 mm

Step-by-step explanation:

since the figures are similar then the ratios of corresponding sides are in proportion, that is

$\frac{v}{20}$ = $\frac{28}{35}$ ( cross- multiply )

35v = 560 ( divide both sides by 35 )

v = 16

It is according to the laws of mathematics that you cannot add or subtract fractions that have different denominators to each other. So you need to make your fractions having the same denominator so that they are able to be added or subtracted (hence the equivalent fractions - making the denominators the same are making the fractions equivalent)
