So we have to put the value of 1:3 in a ratio
1 : 3
= 3:y
Ask yourself what do I have to multiply one by to get three ( the answer is three)
Because one side is multiplied by three, you have to multiply the right hand side by three to get y
3*3 is 9
Therefore, the y for 3 hours is 9
Then, we have to make another ratio
1:3
= 5:x
Ask yourself what do I have to multiply by one to get five (the answer is five)
So you multiply the other side by five as well
3*5=15
Therefore, the y for five hours is 15
T=2(747)/9 and b=7(747)/9
t=166, b=581
Chlamydia – Chlamydia is a bacterial STD. It can often be treated with just a single round of antibiotics. Gonorrhea – Like chlamydia, gonorrhea is caused by bacteria that can usually be treated with antibiotics, however, there have recently been some cases of gonorrhea that are resistant to antibiotics.
First, 7 x 10 = 70, you now have 30 left, 7 x 4 = 28. 10 + 4 = 14 with a remainder of 2. That is your answer though many would put “14 2/7” as the answer with the 2 over the 7 because its the remainder over what was getting divided first. thus 100/7 is has the remainder of 2 with the quotient 14.
