The required estimation of 11 4/5 divided by 3 1/5 is 4.61.
Given that,
To determine the estimation of 11 4/5 divided by 3 1/5.
<h3>What is arithmetic?</h3>
In mathematics, it deals with numbers of operations according to the statements.
In the given question we have given, 2 mixed fractions we have to determine the simplified fraction by dividing one from the other, as stated in the question.
Simplification,
11 + 4 / 5 = 59 / 4
3 + 1 / 5 = 16 / 5
11 4/5 divided by 3 1/5 estimation,
= ( 59/4 ) / (16 / 5)
= 59 * 5 / 4 * 16
= 4.61
Thus, the required estimation of 11 4/5 divided by 3 1/5 is 4.61.

Write the appropriate rate:
3 1/2 cups flour 7/2
---------------------------- = ---------- = 2 1/3 cups flower per dozen muffins.
1 1/2 dozen muffins 3/2
3. c x 3 = 4
c x 3/3 = 4/3 ( Use the inverse of operation and divide both sides of the equation to isolate the variable)
c = 4/3
c = 1.333333333, 3/4 = 0.75
