1. A box contains 56 apples and some oranges. the ratio of the number of apples to the number of oranges is 8 : 3. Find the initial number of oranges in the box.
Jawaban:
There is 21 oranges.
Penjelasan dengan langkah-langkah:
Ratio for Apples (a) is 8
Ratio for Oranges (o) is 3
Total Fruit in the Box (t) is 56
To find how many oranges in that Box, we can use this formula:
[tex] \frac{o}{a } \times t =oranges \: we \: have[/tex]
So that can be:
[tex] \frac{3}{8} \times 56 = 21[/tex]
So we have 21 oranges in that Box

The buttons in the box B is :
(Jumlah tombol di kotak B adalah :)
35 + 15 = 50 buttons
All of the buttons is :
(Jumlah semua tombol adalah :)
7/5 × 50 = 70 buttons
The buttons in the box A is :
(Jumlah tombol di kotak A adalah :)
70 - buttons in box B
(70 - tombol di kotak B)
70 - 50

17. Chai Yun had a box of cookies. The ratio of the number of chocolate chip cookiesto the number of peanut butter cookies was 7:5. She gave 15 chocolate chipcookies to her friends and the ratio of the number of chocolate chip cookiesto the number of peanut butter cookies in the box became 11:10.a How many peanut butter cookies were in the box?How many chocolate chip cookies were left in the box in the end?
Jawab:
a. There were 50 peanut butter cookies in the box.
b. There were 70 - 15 = 55 chocolate chip cookies left in the box in the end.
Penjelasan dengan langkah-langkah:
Let's c represents Chocolate chip cookies and p represents Peanut butter cookies original quantity.
c : p = 7 : 5
c = 1.4 p
Then c - 15 : p = 11 :10
c - 15 = 1.1 p
c = 1.1p + 15
1.4p = 1.1p + 15
0.3p = 15
p = 50
c = 1.4p = 1.4 x 50 = 70
So,
a. There were 50 peanut butter cookies in the box.
b. There were 70 - 15 = 55 chocolate chip cookies left in the box in the end.
