0.5,1: 5,0.35,12/25,4/5 in least to greatest

First we must convert all the values to one mathematical state. We shall convert each to its decimal figure.

a) 0.5 is already a decimal so we leave it alone

b) 1: 5 when simplified makes  1/6  = 0.16

c) 0.35 is already a decimal so we will not touch it.

d) 12/25  = 0.48

e) 4/5 = 0.8

so now we arrange these from the least to greatest:

b, c, a, d, e,

 now we equate this with the original values so the answer will be:

1:5,  0.35,  0.5,  12/25,  4/5

step-by-step explanation:

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
