2 * 22/7 * r = 44
r = 44 * 1/2 * 7/22 (bring all numbers one side)
r = 2 * 1/2 * 7 (cancelling out 44 & 22 which gives 2)
r = 7 ( cancelling 2 & 2 & hence 7 is remaining)

2*22/7*r = 44 {This question is similar to the topic SIMPLE EQUATIONS, where 'r' being the variable has to be found}
22/7r = 44/2 { In this step, we take 2 to the other side and keeping in mind that multiplication changes to division '2*' to '/2'}
22/7r = 22 { Since, 44/2=22, we form the following equation}
r = 22*7/22 { We leave 'r' and take 22/7 to the other side forming, 22*7/22}
r = 7 { Therefore, the answer we get is 7}
Hope you understood the concept,
Thanks,
