First, find common denominators. Remember that what you multiply to the denominator, you multiply to the numerator too:
(3/8)(5/5) = 15/40
(3/5)(8/8) = 24/40
Simplify
15/40 + 24/40 = 39/40
39/40 is your answer
hope this helps
3/8 + 3/5 = <u>39/40</u> and 39/40 Can't be <em>simplified</em>
Answer:
134 children and 120 adult plates were served
Step-by-step explanation:
let the children mean be x
Let the adult meal be y
If fourteen less children’s meals were served than adult meals at a barbecue, then;
y = x - 14 .... 1
IF Children plate were 1.50 each and adult plates were 2.00 each with a total of 441 in amount then;
1.5x + 2y = 441 .... 2
Substitute 1 into 2;
1.5x + 2(x-14) = 441
1.5x+2x-28 = 441
3.5x = 441+28
3.5x = 469
x = 469/3.5
x = 134
Recall that y = x - 14
y = 134-14
y = 120
Hence 134 children and 120 adult plates were served
