an elevator can carry either 159 adults or 186 children at one time. Given that 62 children are already in the elevator, how many adults can still get into the elevator?

Carina and Leslie shared some sweets. if Carina received 8 sweets from Leslie, the ratio of the number of sweets she had to the number of sweets Leslie had would be 3:1. If Leslie received 24 sweets from Carina, he would have the same number of sweets from Carina. What was the total number of sweets shared?

Jug X & Jug Y contained some apple juice. if 2/7 of the apple juice from jug Y was poured into Jug X, the ratio of the amount of apple juice in Jug Y to that in Jug X would be 10:13. What was the ratio of the amount of apple juice in jug Y to the amount of apple juice in Jug X at first?

2 teams were having a tug of war. The number of members in team A was 6/7 of the number of members in team B. After 2 members left team B due to injury, the number of members in team A was 7/8 of the number of members in team B. Find the number of members in Team A.

The number of members in Team A remains the same --> equalize the numerators.

At first, Team A = 6/7 Team B = 84/98 Team B
In the end, Team A = 7/8 Team B = 84/96 Team B

So, there are 84 members in Team A

cheers.

Sorry, can this be solved using model method?

5/11 of the children at a party like chocolate ice cream. 1/3 as many children like vanilla ice cream as those who like strawberry ice cream. There are 182 more children who like chocolate ice cream than vanilla ice cream. How many children are there at party altogether?

Pls help to advise if can solve this via model or via fraction method?
Thanks

you can use any approach - fraction, ratio, model, units..

using fraction:
children who like chocolate ice-cream --> 5/11 total
children who like vanilla and strawberry ice-cream--> 6/11 total
children who like vanilla ice cream --> 1/4 x 6/11 = 6/44 total
children who like strawberry ice cream --> 3/4 x 6/11 = 18/44 total
5/11 - 6/44 = 14/44
14/44 total --> 182
Total number of children = 182/14 x 44 = 572

using ratio:
children who like chocolate : total : vanilla & strawberry = 5 : 11 : 6 = 10u : 22u : 12u
children who like vanilla : strawberry = 1 : 3 = 3u : 9u (total 12u)
10u - 3u = 7u --> 182
total number of children = 22/7 x 182 = 572

cheers.

You wrote \"children who like vanilla ice cream --> 1/4 x 6/11 = 6/44 total \"
can u help to explain how the 1/4 is being derived? Thanks
