Answer:
8 loaves
Step-by-step explanation:
Possible english translation:
Find the largest number of children among whom 32.48 and 56 loaves can be distributed simultaneously, so that in either case each receives the same amount. How many loaves will each child receive?
<u>Solution:</u>
The max amount each one will receive from either 32, 48, or 56 loaves would basically be the HCF (highest common factor) of the 3 numbers.
To get HCF of the 3 numbers given, we follow the rule below:
- Get prime factorization of each number (express the number as product of primes by dividing
- Then we take the smallest power of shared factor
We show this below:
32/2 = 16/2 = 8/2 = 4/2 = 2
So,
32 =
48/2 = 24/2 = 12/2 =6/2 = 3
So,
48 =
56/2 = 28/2 = 14/2 = 7
56 =
Common factor is only "2" (in all 3 numbers) and the lowest powered one is 2^3, so the <u>HCF is 8</u>
Answer:
The percentage increase in Jayana's postcard collection is 15%
Step-by-step explanation:
Jayana had 20 postcards last year
With 3 more postcards this year
From the given equation Quantity = Percent x Whole
Here;
Let P = Percent/100%
Quantity = Increment in postcard = 3 postcards
Whole = The total postcards from last year = 20 postcards
Hence,
3 postcards = P x 20 postcards
P = 3/20 = 0.15
Recall P = Percent/100%
∴ Percent = P x 100% = 0.15 x 100% = 15%
The percentage increase in Jayana's postcard collection is 15%
