720 naira was shared between Hassan and Ali such that Ali got 70 naira more than Hassan. How much did Hassan get?
Let's call the amount Hassan got "x".
According to the problem, Ali got 70 naira more than Hassan, so Ali got:
x + 70
We know that together they received 720 naira, so we can set up an equation:
x + (x + 70) = 720
Simplifying this equation:
2x + 70 = 720
Subtracting 70 from both sides:
2x = 650
Dividing both sides by 2:
x = 325
So Hassan got 325 naira.
The difference between two numbers is 120. If the smaller number is 720. What is the larger numbers?
If the difference between two numbers is 120, and the smaller number is 720, we can find the larger number by adding the difference to the smaller number.
So the larger number is:
720 + 120 = 840
Therefore, the larger number is 840.
Express 0.8 in ratio terms
To express 0.8 in ratio terms, we can write it as a fraction over 1:
0.8 = 0.8/1
To write this as a ratio, we can multiply both the numerator and denominator by 10 to get rid of the decimal:
0.8/1 = 8/10
We can simplify this ratio by dividing both the numerator and denominator by their greatest common factor, which is 2:
8/10 = 4/5
Therefore, the ratio of 0.8 is 4:5.
The ratio of girls to boys is 5:3. If there are 60 boys. How many girls are in the school?
If the ratio of girls to boys is 5:3, this means that for every 5 girls, there are 3 boys. We can use this ratio to find the number of girls in the school, given that there are 60 boys:
First, we need to find how many groups of 3 boys there are in 60. We can do this by dividing 60 by 3:
60 ÷ 3 = 20
This means that there are 20 groups of 3 boys in a total of 60 boys.
Since the ratio of girls to boys is 5:3, for every 3 boys there are 5 girls. So for 20 groups of 3 boys, there are:
20 × 5 = 100 girls
Therefore, there are 100 girls in the school.
