Need help on this questionWatch
If any of you know ratio well I’m going to put the question here and could anyone reply with how to work this question out and how the answer is ‘ 220 sweets’!!!!
Adrian, Ben and Charlie share some sweets in the ratio 79
Charlie got 22 more sweets than Adrian
Work out the total amount of sweets:
( the website said 220 sweets but didn’t explain how so can someone please reply and explain)
The ratio of sweets that Adrian and Charlie have shows that A/C = 7/9 , so A = (7/9) * C.
Then, as Charlie got 22 more sweets than Adrian, C = A + 22 . Substitute A = (7/9) * C into this equation and you'll have an expression you can use to work out how many sweets Charlie has.
Then, use this to work out how many Adrian has using A = (7/9) * C.
Finally, you know the ratio of Ben's sweets to either Charlie or Adrian so you can figure out how many he has.
