Express the ratio 16 days to 4 weeks as a fraction in simplest form.

We presume you want a fraction that is a pure number, so both units of time need to be the same.

... (16 days)/(4 weeks) = (16 days)/(28 days) = 16/28 = 4/7

Comment on reducing fractions

Some calculators will reduce fractions for you. When you do it without benefit of a calculator, it helps immensely if you know your times tables. Here,

... 16 = 4×4

... 28 = 4×7

so ...

... 16/28 = (4×4)/(4×7)

... = (4/4)×(4/7)

... = 1×(4/7) = 4/7

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
