Danielle's friend called her asking for a piece of rope that is 3/10 of a yard long. danielle has one that is 5/7 of a yard long. how can danielle figure out if this is long enough for her friend to use?
a.
subtract the numerators and denominators to make a new fraction.
b.
change 5/7 to a mixed number.
c.
multiply 3/10 by 5/7.
d.
find a common denominator. multiply and divide by suitable numbers and make each fraction to have common denominator and then compare the numerators.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)  

wait nvm i know the correct answer now its 100%   81 square feet
