Apologies, but there is no map...?
31/4
This can be changed into 7 3/4.
To get the whole number 8, you only need to add 1/4.
7 3/4 + 1/4 = 7 4/4 = 8
The answer is 1/4.
Sabrina picked 42 apples because the word times indicates multiplication and 6x7 is 42
Assume
Combining the fractions on the right hand side gives
The fractions will be equal as long as the their numerator are equal:
Polynomials are equal to one another if the coefficients of like terms are equal:
Solving this, you'd get and , so that your answer would be (26, -23).
- - -
Instead of solving the system of equations above, there is a trick that involves picking so that some terms disappear and solving for either is much faster.
At the point where we have
notice that setting will eliminate . Doing so, we get
while setting would give
