$3.52 is the value of 4 notebooks
find the cost of one by dividing the 6.16 and 7 then take that amount and times it by 4.
6.16 divided by 7 = 0.88 .88 times 4 = 3.52
i got to write a proportion
@Black_ninja123 0.94? is wrong
or you could set it up as a proportion... 7/6.16 = 4/x --- 7 notebooks for 6.16 = 4 notebooks for $x
Yea 0.94 is wrong sorry
7/6.16 = 4/x --- cross multiply 7x = (6.16)(4) can you finish and solve for x
uhhhg i dont understand so many replies
its just writing proportions
proportions are nothing but equivalent fractions
7/6.16 = 4/x --- 7 notebooks for 6.16 = 4 notebooks for x dollars CROSS MULTIPLY (7)(x) = (6.16)(4) 7x = 24.64 x = 24.64/7 x = 3.52
x=(4/6.80) x 33
4 glue sticks cost \$6.80 Which equation would help determine the cost of 3 glue sticks?
x=(4/6.80) x 3 meaning that bc the 4/6.80 is in parenthesis then you do that first to find the cost of one, then you take the quotient of that and times it by three to find the cost.
i dont understand? wht?
what grade are you in?
hmmmmmmm lets see uhhh not ur business
