Express 81/3% as a simple fraction
81/3% can be simplified as follows:
81/3% = 81/(3/100)
To simplify further, we can divide 81 by 3/100:
81 ÷ (3/100)
To divide fractions, we multiply the numerator by the reciprocal of the denominator:
81 × (100/3) = 8100/3
Simplifying the resulting fraction by dividing both numerator and denominator by 3, we get:
8100/3 = 2700/1
So, 81/3% is equal to the simple fraction 2700/1.
Express 8⅓% as a simple fraction
To express 8⅓% as a simple fraction, we first need to convert the mixed number 8⅓ to an improper fraction.
To do this, we multiply the whole number (8) by the denominator of the fraction (3) and add the numerator (1). Then, the result becomes the new numerator of the improper fraction, and the denominator remains the same.
8⅓ = (8 × 3 + 1)/3 = 25/3
Now, we can express 8⅓% as a simple fraction:
8⅓% = (25/3)% = (25/3) / 100
To simplify further, we multiply the numerator by 1/100:
25/3 × 1/100 = 25/300
So, 8⅓% can be expressed as the simple fraction 25/300.
The average age of 5 boys is 12 years if one of them is 10 year old, what is the average age of the remaining boys
The total age of the 5 boys is 12 years old per boy * 5 boys = 60 years.
If one of them is 10 years old, then the total age of the remaining boys is 60 years - 10 years = 50 years.
To find the average age of the remaining boys, we divide the total age by the number of remaining boys.
Since there are 4 remaining boys, the average age of the remaining boys is 50 years / 4 boys = 12.5 years.
The ratio of boys to girls in a school in 3:5 if there are 60 girls,how many boys are in the school
Given that the ratio of boys to girls in the school is 3:5, we can set up a proportion to find the number of boys.
The ratio of boys to girls is 3:5, which can be represented as 3x:5x, where x is a common factor.
We know that there are 60 girls, so 5x = 60.
To solve for x, we divide both sides of the equation by 5: x = 60/5 = 12.
Now that we have the value of x, we can find the number of boys: 3x = 3 * 12 = 36.
Therefore, there are 36 boys in the school.
