4 1/5 divided 1 2/5
21/5 x 7/5 = ?
You're half right.
You need to invert the second fraction to multiply.
(21/5) * (5/7)
Ms.Sue,is the ans 3?
To divide 4 1/5 by 1 2/5, we first need to convert the mixed numbers into improper fractions.
To convert 4 1/5 into an improper fraction, multiply the whole number (4) by the denominator (5) and add the numerator (1). This gives us (4 x 5) + 1 = 21. The denominator remains the same, so the improper fraction is 21/5.
Similarly, to convert 1 2/5 into an improper fraction, multiply the whole number (1) by the denominator (5) and add the numerator (2). This gives us (1 x 5) + 2 = 7. The denominator remains the same, so the improper fraction is 7/5.
Now that we have both numbers as improper fractions, we can divide them by multiplying the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is obtained by swapping the numerator and denominator.
So, we have (21/5) divided by (7/5). To multiply fractions, multiply the numerators together and the denominators together. Thus, (21/5) x (5/7) = (21 x 5) / (5 x 7) = 105/35.
However, this fraction can be simplified further. Both the numerator and the denominator have a common factor of 7. Divide both the numerator and the denominator by 7, and we get 105/35 = (105 รท 7) / (35 รท 7) = 15/5.
Thus, the division of 4 1/5 by 1 2/5 results in 15/5.
