PLEASE HELP WITH ALL PROBLEMS WILL MARK BRAINLIEST PLUS ALL THESE POINTS

Step-by-step explanation:

14.Since the most common denominator is 40 lets multiply all the denominators to equal all to 40

Evita:24/40

Jack:25/40

Keisha:30/40

Sinjo:20/40

Therefore Keisha drank the most bottles

15. The most common denominator for 5/8 and 2/3 is 24 lets have both denominators equal to 24

5/8 -> 15/24

2/3-> 16/24

Therefore flour is the greater amount

16.Multiply the denominators equal to 6 since thats the least common denominator

1/2->3/6 | 2/3->4/6

Therefore peanuts is the greater ingredient amount

17.If you multiply both the numerator and denominator of a fraction by the same non-zero number, the fraction remains unchanged in value. Therefore, equivalent fractions can be created by multiplying (or dividing) the numerator and denominator by the same number.

18.We can compare fractions with unlike denominators by finding the least common denominator and making equivalent fractions. When the denominators are the same, the number with the larger numerator is the larger fraction.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
