Hi Mathizzzfun & Alderbaran,


Many thanks for the solutions! I'm clear now...

Btw, I've got one more please.

Miss Chew bought a total of 60 mangoes and oranges. The ratio of the amount spent on mangoes to that of the oranges is 4:1. The mangoes cost $72. If a mango cost twice as much as an orange, find the ratio of the number of mangoes to the number of oranges.

Thank you.

Hi

since the question is asking for Ratio of number of mangoes to oranges, a lot of information is redundant.

Total cost of mangoes : oranges = 4 : 1
Since cost of one mango : one orange = 2 :1

Number of mangoes : Oranges = 2 : 1

cheers.

hi all,


Need help on this question. Thanks

A skirt cost 1/3 as much as the cost of each pair of shoes. If Tricia bought 2 shirts and 5 pair of shoes for $799, how much did she pay for each shirt?

Thanks

Hi

I presume that it is \"skirts\" and not \"shirts\" in the second sentence.

This model will help

Thanks

Shoes = 3 Shirts

Therefore, 15 Shirts (5 Shoes = 15 Shirts) + 2 Shirts = $799

Therefore, 17 Shirts = $799

So, 1 shirt = $799 ÷ 17 = $47

A skirt cost 1/3 as much as the cost of each pair of shoes. If Tricia bought 2 skirts and 5 pair of shoes for $799, how much did she pay for each skirt?

Thanks

1 Sk --> 1 u
2 Sk --> 2 x 1 = 2 u

1 Sh --> 3 u
5 Sh --> 5 x 3 = 15 u

17 u --> 799

1 u --> 1/17 x 799 = $47

It was $47.

Thanks

2 shirts + 5 pair of shoes = $799

If a shirt cost one-third as much as the cost of each pair of shoes, that means that each pair of shoes cost as much as three shirts. Convert all shoes to shirts.

2 shirts + 15 (5x3) shirts = $799

17 shirts = $799
1 shirt = $799/17 = $47
