She then worked out the actual answers. Even though the estimated answers were the same,
Jodi found that the actual answers were very different from each other.

Question 1.
In which case is the estimate closer to the actual answer? Explain why.
Answer:
In the estimate a Jodi is closer to the actual answer,

Explanation:
In the estimation a Jodi is closer to the actual answer,
why because while working out with the answers even though
the estimated answers were the same Jodi found that the actual answers
are differing why because while rounding the estimates the closer value
is method (a) as 2,892 has greater value than 2,743.

Question 4.
An organic farmer buys a piece of land. She plants tomatoes on \(\frac{5}{9}\) of the land and green beans on \(\frac{1}{12}\) of the land. She plants potatoes on the remaining piece of land. What fraction of the land does she plant with potatoes?
Answer:
\(\frac{13}{36}\) of the land that she plant with potatoes
Explanation:
An organic farmer buys a piece of land.
She plants tomatoes on \(\frac{5}{9}\) of the land
and green beans on \(\frac{1}{12}\) of the land.
She plants potatoes on the remaining piece of land.
total land = 1
Tomatoes = \(\frac{5}{9}\)1
Green beans = \(\frac{1}{12}\)1
potatoes = 1 – (\(\frac{5}{9}\) + \(\frac{1}{12}\))
= \(\frac{20+3}{36}\)
= \(\frac{36-23}{36}\)

Question 6.
Reggie and Jay go for a walk every morning. Reggie walks 2\(\frac{1}{4}\) miles. Jay walks 1\(\frac{3}{8}\) miles less than Reggie. What is the total distance they walk every morning?
Answer:
3 \(\frac{1}{8}\) is the total distance they walk every morning
Explanation:
Reggie and Jay go for a walk every morning. Reggie walks 2\(\frac{1}{4}\) miles.
2\(\frac{1}{4}\) = \(\frac{9}{4}\)
Jay walks 1\(\frac{3}{8}\) miles less than Reggie.
1\(\frac{3}{8}\) = \(\frac{11}{8}\)
\(\frac{9}{4}\) – \(\frac{11}{8}\)
= \(\frac{18-11}{8}\) = \(\frac{7}{8}\)
Total distance
\(\frac{9}{4}\) + \(\frac{7}{8}\)

Question 7.
Alicia uses \(\frac{3}{4}\) gallon of paint to paint her room. Becca uses \(\frac{4}{5}\) gallon more than Alicia to paint her room. How many gallons of paint do they use altogether?
Answer:
= \(\frac{23}{10}\) gallons of paint that they use altogether
Explanation:
Alicia uses \(\frac{3}{4}\) gallon
Becca uses \(\frac{4}{5}\) gallon
\(\frac{4}{5}\) > \(\frac{3}{4}\)
so, Becca =
\(\frac{4}{5}\) + \(\frac{3}{4}\)

Altogether
\(\frac{3}{4}\) + \(\frac{31}{20}\)
