The sum of the numbers should total to 1. Let us say that
x is the missing number, therefore:
x + ¼ + ¼ + 1/5 = 1
x = 1 – ¼ - ¼ - 1/5
The numbers should have similar denominator:
x = 20/20 – 5/20 – 5/20 – 4/20
x = 6/20
<span>x = 3/10</span>
2*3=6 children Mrs Gomez has
6-2= 4 girls she has
pink carnations/ blue carnations= 4/2=2
⇒ numbers of pink carnations= 2* blue carnations
⇒ 12 pink carnations and 6 blue carnations
"Half of a number decreased by 27" can be displayed as:
<u>1/2x - 27</u>
Supplementary angles are 180 in total, so to find the answer you do 180-10, which equals 170. The answer is 170
