What number is the same ratio to 64 as 5 is to 8
Let's represent the unknown number as "x". We are told that the ratio of this unknown number to 64 is the same as the ratio of 5 to 8. Mathematically, this can be written as:
x/64 = 5/8
To solve for x, we can cross-multiply:
8x = 64 * 5
8x = 320
Now, we can divide both sides by 8 to isolate x:
x = 320/8
x = 40
Therefore, the number that is in the same ratio to 64 as 5 is to 8 is 40.
In a class there are 15 girls and 35 boys what is the ratio girls to boys
The ratio of girls to boys in the class can be calculated by dividing the number of girls by the number of boys:
Ratio = Number of girls / Number of boys
Ratio = 15 / 35
Simplifying this ratio, we can divide both the numerator and denominator by 5:
Ratio = 3 / 7
Therefore, the ratio of girls to boys in the class is 3:7.
Express 5 and half:2 half as a ratio of whole numbers
To express 5 and a half (5.5) to 2 and a half (2.5) as a ratio of whole numbers, we need to convert the decimals to fractions.
5.5 can be expressed as 11/2 (two halves in one whole, and adding 5 wholes to it)
2.5 can be expressed as 5/2 (two halves in one whole, and adding 2 wholes to it)
Now we can write the ratio in terms of whole numbers:
Ratio = 11/2 : 5/2
To make the ratio as a ratio of whole numbers, we need to multiply each part by 2 to get rid of the denominators:
Ratio = (11/2) * 2 : (5/2) * 2
Simplifying, we get:
Ratio = 11 : 5
Therefore, the ratio of 5 and a half to 2 and a half, expressed as a ratio of whole numbers, is 11:5.
48 naira was shared between obi and emeka in the ratio of 3:5 how much did obi received
To find out how much Obi received, we'll use the given ratio of 3:5 and the total amount of 48 naira.
We can think of the ratio as 3 parts to 5 parts. The total number of parts is 3 + 5 = 8.
To calculate how much each part is worth in terms of naira, we divide 48 by 8:
48 ÷ 8 = 6
Therefore, each part is worth 6 naira.
Since Obi's share is in a ratio of 3 parts, we multiply the value of one part by 3:
6 x 3 = 18
Obi received 18 naira.
Divide 45 Kobo between taiwo and kehinde in the ratio of 4:5
To divide 45 Kobo between Taiwo and Kehinde in the ratio of 4:5, we first need to find the total number of parts in the ratio.
The total number of parts in the ratio of 4:5 is 4 + 5 = 9.
Next, we divide the total amount of 45 Kobo by the total number of parts (9) to find the value of each part:
45 Kobo ÷ 9 = 5 Kobo
Therefore, each part is worth 5 Kobo.
To find out how much Taiwo and Kehinde will receive, we multiply the value of each part by the corresponding ratio:
Taiwo: 4 parts x 5 Kobo = 20 Kobo
Kehinde: 5 parts x 5 Kobo = 25 Kobo
Taiwo will receive 20 Kobo and Kehinde will receive 25 Kobo.
