How you taken 30%.

We can solve it in a very simple way as follows:

Expenses in FUEL & TRANS is how much increased to that of expenses in TAXES.

We can find the increase in percentage like this->

586-451/451 x 100% = 30%.

i.e 100/130 = 10/13 or 10:13.

I'm not getting how to calculate the ratio 451/586?

451/586.
Take 451 as 450 and 586 as 590.

Because as per approximation or numbers whatever rule it is ex: if the last digit number comes in b/w 1-5 i..e 451, 252, 555..it becomes 450 250 550
where as if the last digit no comes in b/w 6-10 like 456, 227, 228, 449...then take it As 460, 230, 230, 450.

Now 450/590
45/59

10/13.

Hey, @Ami you divided 586 by 451 and you got 1.3.

Actual is 451 divided by 586. You have to just reciprocal it. Then simply you will get 1:1.3.

That's it yar.

How did you get the 1/1.29 answer particularly to 1?is it automatically to put 1 on 1.29 as a numerator?

When you divide x by y (x/y) you put 1 in the place of y and the quotient in the place of x.

Eg: 4 divided by 2 (or 4/2) is 2... actually it is 2 by 1 (or 2/1)..but here the denominator 1 has no real meaning.. so we take the answer as 2 alone.

However if you take the numerator as the divisor (in this case 451) and denominator as dividend (586) you need to put 1 in place of the divisor (i.e, numerator) and quotient in the place of dividend (i.e, denominator).

Ok we got 1/1.3. But how we get 10:13?
Please can anyone explain in a ease way?

Consider single year(1998) taxes and fuel, expenditure and calculate the ratio between them.

Taxes: Fuel and expenditure.

98:83 = 98/83 = 10/13.

@Sonam its simple.

We just need to multiply numerator and denominator by 10 so as to eliminate the decimal. We need fraction as a whole number.

1*10/1.3*10 = 10/13.
