<span>the ratio in which the sweets are distributed are 4:5:7.
total number of portions are 4 + 5 + 7 = 16.
we are told that Seth has 18 more sweets than Frank.
if we take the ratio of Frank to Seth its 4:7. Seth has 3 portions more than Frank. 3 portions are equivalent to 18 sweets. Therefore 1 portion is equal to 6 sweets. altogether there are 16 portions ,
therefore total number of sweets are 16 x 6 sweets = 96 sweets. they shared a total of 96 sweets</span>
How long is one lap? Multiply that by three and convert it into meters.

<h3>How to Simplify Fractions?</h3>
We want to simplify the expression;
[(4a + 4)/2a] * [a²/(a + 1)]
This expression can be further reduced to;
[(4a + 4)/2] * [a/(a + 1)]
Factorizing the numerator to get;
[(4(a + 1)/2] * [a/(a + 1)]
(a + 1) will cancel out to get;
2a
