Question

5:35anda:30, then find the value of a ​

Answer 1

5:35=1:7

similarly a:30=1:7

so a=30/7

Answer 2

Answer:

$a=\frac{30}{7}$

Step-by-step explanation:

I am assuming that 5:35 is proportionate to a:30 [i.e. 5:35::a:30] as I have a feeling that i may have misunderstood the question

5:35= $\frac{5}{35}$, and $a$:30= $\frac{a}{30}$

$\frac{5}{35}$=$\frac{1}{7}$   [Simplifying the fraction]

$\frac{1}{7}$= $\frac{a}{30}$

30=7$a$    [Cross multiplication]

And $a=\frac{30}{7}$
