The cost of the fabric is $1.31. What would you expect to pay for a similar piece of fabric that is 18 inches by 42 inches?
Answers
Answer: Calculate areas for 2 rectangles;
21*9= 189
18*42= 756
make an equation with data you have;
If 189 cost $1.31
756 cost $x
____________
756 *1.31 / 189 = $5.24 cost for second fabric
Second way;
(18x42) / (21x9) = 4 x 1.31 = $5.24

Karina is baking bread. She buys a small bag of flour that contains 2[tex]\frac{2}{3}[/tex]cups of flour. The recipe calls for 2 [tex]\frac{5}{7}[/tex]cups of flour. Does she have enough flour to bake the bread? Explain how she can compare the fractions to know for sure.
Answers
Answer:
to compare she must calculate...
1) ((2*3)+2)/3 she get 2.666
2) ((2*7)+5)/7 she get 2.714
by approximation the two are the same and she had enough flour.
Using approximation, the two are the same and she has enough flour.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Given that Karina buys a small bag of flour that contains [tex]2\frac{2}{3}[/tex] cups of flour. The recipe calls for [tex]2\frac{5}{7}[/tex] cups of flour.
1) [tex]2\frac{2}{3}[/tex] cups of flour.
= ((2 x 3)+2)/3
= 2.666
Hence, she get 2.666
2) [tex]2\frac{5}{7}[/tex] cups of flour.
= ((2x 7)+5)/7
= 2.714
Hence, she get 2.714
Using approximation, the two are the same and she has enough flour.
