00:00 - 00:59 | Indian question if a ratio B that one is equals to 4 ratio 5 and b ratio see that one is equals to 2 ratio 3 then we have to find out the value of A ratio Si so here it is given a ratio B or it can also be written as a / be that one is equals to it is 4 ratio 5 that one can also be written as 4 / pipe similarly here it is be divided so ja be divided so that one is equals to 2 / 3 so here in order to find out the ratio of a and b first try to make this be part to be equal in both the ratios so here it is 5 and then it is to show here if we multiply this 5 by 2 then we get 10/10 similarly if we multiply this 2 by 5 year we simply get 10 so here in order to do that we multiply the numerator and denominator of distraction by to |

01:00 - 01:59 | Sohail Tu and then divided by 2 so here we get 4 into two is 8 and then divided by 5 into two is it is 10 similarly here here if we multiply the numerator and denominator by 5 so here we get is equals to 2 into 10 and then divided by 3 into 5 and that one is equals to 15 so here in both the ratio of the parties same which is 10 soap hear this one can also be written as a ratio B ratio see that one is equals to 8 ratio 10 which is here this might be part and then tissue see here it is 15 so now we can simply right that the ratio of a and see that one is equals to 8 and then ratio here it is it is it and then 15 so we get the ratio to be a tissue 15 and here that's the answer and in the given question here option B is the right answer |

**Introduction**

**RATIO: The ratio of two quantities of the same kind and in the units is a fraction that shows how many times the one quantity is of the other.**

**RATIO IN THE SIMPLEST FORM: A ratio `a : b` is said to be in the simplest form if its antecedent a and consequent b have no common factor other than 1.**

**In a ratio we compare two quantities. The comparison meaningless if the quantities being compared are not of the same kind.**

**RATIO: The ratio of two quantities of the same kind and in the units is a fraction that shows how many times the one quantity is of the other.**

**The order of the terms in a ratio `a : b` is very important. The ratio `3 : 2` is different from the ratio `2 : 3`.**

**Divide 108 in two parts in the ratio `4 : 5`.**

**If `(4x+5) : (3x+11) = 13 : 17` find the value of `x`.**

**Comparison of ratios**

**EQUIVALENT RATIOS A ratio obtained by multiplying or dividing the numerator and denominator of a given ratio by the same number is called an equivalent ratio.**
