Answer:
14 : 21
Step-by-step explanation:
---> 2:3 ----> 2+3=5
---> Stick's length = 35 inches
<u />
<u>For the first portion</u>
2/5 x 35
2/1 x 7
= 14 inches
<u>For the second portion</u>
3/5 x 35
3/1 x 7
= 21 inches
To confirm: 14 + 21 = 35 inches
14 : 21
Divide both by 7
2 : 3
Step-by-step explanation:
2x-5=2x-6. First you collect like terms

Answer:
1 7/15
Step-by-step explanation:
2-1=1
then you make 2/3 and 1/5 have the same denominator -
5*3=15
?/15 ?/15
multiply 2 by 5 which is 10, so 10/15
then multiply 1 by 3 which is 3/15
subtract 3/15 from 10/15 which is 7/15
