Tiga dua puluh sembilan per dua puluh empat menjadi pecahan terkecil
Answer (4)
To do this task the best way is always add both "sides" of ratio and divide whole group by this sum. sum=4+7=11 33:11=3 Now we know how much is 1 and we can multiply by 4 and by 7 to find the answer. 3 4=12 - first group 3 7=21 - second group
Your result is ok.
The correct answer is:
12:21.
Explanation :
Let x be the part of our 33 photos that represents 4 in our ratio. Then the second part of the ratio, the part that represents 7, will be 33-x, the remaining number of photos.
This gives us the ratio
33 − x x
Since we know we want this ratio to equal 4:7, we can set up a proportion:
33 − x x = 7 4
To solve this, we cross-multiply:
x(7) = (33-x)(4)
7x = (33-x)(4)
We use the distributive property on the right:
7x = 33 4-x 4
7x = 132-4x
Add 4x to each side:
7x+4x = 132-4x+4x
11x = 132
Divide both sies by 11:
11x/11 = 132/11
x = 12
The smaller portion of photos, that represents the 4 in our ratio, is 12. This leaves 33-x=33-12=21 for the larger portion of photos. This gives us the ratio 12:21.
The photos are divided into two groups: 12 and 21, following the ratio of 4:7. This means that the smaller group has 12 photos, and the larger group has 21 photos. The ratio is confirmed as 4:7.

Jawab:[tex]\frac{329}{24}[/tex] Untuk menyederhanakan pecahan, kita perlu mencari Faktor Persekutuan Terbesar (FPB) dari pembilang (329) dan penyebut (24). Kemudian, bagi pembilang dan penyebut dengan FPB tersebut. Faktor dari 329 adalah 1, 7, 47, dan 329.Faktor dari 24 adalah 1, 2, 3, 4, 6, 8, 12, dan 24.FPB dari 329 dan 24 adalah 1. Karena FPB-nya 1, pecahan 329/24 tidak dapat disederhanakan lebih lanjut.Jadi, pecahan 329/24 sudah merupakan pecahan terkecil.
