Judi's share was  (7 x $2.50) =  $17.50 .

That was really one share out of eight.
So the total bill was

                             (8 x $17.50) =   $140.00 .

Margaret’s bottle of shampoo is 7/8 full. She uses 1/3 of the shampoo in the bottle to wash the dog. Estimate what fraction of s
AleksandrR [38]

Fraction of shampoo left = \frac{13}{24}

Solution:

Given fraction of full shampoo  =\frac{7}{8}.

Fraction of shampoo Margaret used  =\frac{1}{3}

Fraction of shampoo left = Full shampoo – fraction of shampoo used

                                          =\frac{7}{8}-\frac{1}{3}

To make the denominators same do cross multiplication.

                                          =\frac{7\times3}{8\times3}-\frac{1\times8}{3\times8}

                                          =\frac{21}{24}-\frac{8}{24}

                                          =\frac{21-8}{24}

                                          =\frac{13}{24}

Hence \frac{13}{24} of the shampoo bottle is left.
