1 1 /3 X 1.80
1 1/3 = 4/3
4/3 x 1.8 = (4 x 1.8)/3 = 7.2/3 = 2.4
To solve the expression 1 1/3 x 1.80, you need to convert the mixed number 1 1/3 into an improper fraction.
First, multiply the whole number, 1, by the denominator of the fraction. In this case, it would be 1 x 3 = 3.
Then, add the product to the numerator of the fraction. 3 + 1 = 4.
Finally, write the sum as the numerator with the denominator unchanged. So, the mixed number 1 1/3 can be written as the improper fraction 4/3.
Next, multiply the improper fraction 4/3 by 1.80. To multiply fractions, you multiply the numerators together and the denominators together.
So, (4 x 1.80)/(3 x 1) = 7.2/3.
Since 7.2 is not divisible by 3, you cannot simplify the fraction further. Therefore, the result of 1 1/3 x 1.80 is 7.2/3, which can also be written as a decimal as 2.4.
