To find out what fraction of the total amount was spent on fuel, we need to follow these steps:
Calculate the Total Amount Spent :
Abdul spent N450 on lunch and N350 on fuel. First, we add these two amounts to find the total amount spent.
Total amount spent = 450 + 350 = N 800
Determine the Fraction of Total Spent on Fuel :
The fraction is calculated by dividing the amount spent on fuel by the total amount spent.
Fraction of total spent on fuel = Total amount spent Amount spent on fuel = 800 350
Simplify the Fraction :
To simplify 800 350 , we need to find the greatest common divisor (GCD) of the numerator and the denominator. The GCD of 350 and 800 is 50.
Simplified fraction = 800 ÷ 50 350 ÷ 50 = 16 7
Therefore, the fraction of the total amount that Abdul spent on fuel is 16 7 .
