find the difference between 303 and 184.
kristin spent $42 on lunch for 7 people. she spent the same amount on each person. how much money did she spend on each person?
solve
7 x 5 = 49 ÷ 7 =
8 x 7 = 21 ÷ 7 =
7 x 12 = 7 ÷ 7 =
9 x 7 = 77 ÷ 7 =
6 x 7 = 35 ÷ 7 =
10 x 7 = 28 ÷ 7 =
7 x 2 = 63 ÷ 7 =

Explanation:

Step1: Find the difference between 303 and 184

$303 - 184=119$

Step2: Calculate the amount Kristin spent on each person

She spent $42$ on 7 people. So, $42\div7 = 6$

Step3: Solve the multiplication and division problems

• $7\times5 = 35$
• $49\div7 = 7$
• $8\times7 = 56$
• $21\div7 = 3$
• $7\times12 = 84$
• $7\div7 = 1$
• $9\times7 = 63$
• $77\div7 = 11$
• $6\times7 = 42$
• $35\div7 = 5$
• $10\times7 = 70$
• $28\div7 = 4$
• $7\times2 = 14$
• $63\div7 = 9$

Answer:

The difference between 303 and 184 is 119. Kristin spent $6$ on each person. The results of multiplications and divisions: $7\times5 = 35$, $49\div7 = 7$, $8\times7 = 56$, $21\div7 = 3$, $7\times12 = 84$, $7\div7 = 1$, $9\times7 = 63$, $77\div7 = 11$, $6\times7 = 42$, $35\div7 = 5$, $10\times7 = 70$, $28\div7 = 4$, $7\times2 = 14$, $63\div7 = 9$
