2:7 = 4:14 because each is equal to 2/7. If you simplify 4:14 by dividing by 2, it simplifies to 2:7.
The Venn diagram shows that rational numbers include all integers (-3, -2, -1, 0, 1, 2, 3,) and all whole numbers (0, 1, 2, 3, 4, 5). Inside the <u>rational </u><u>numbers</u> circle is the <u>integer circle</u>, and the <u>whole numbers </u>circle, which concludes that all integers and whole numbers are rational numbers.
Answer:
fraction represented by model = 5/8
fraction less than model = 2/4
If x is the number,

(The difference or distance between two numbers is the larger one minus the smaller one.)
Set it up like a ratio: pipes on the top and minutes on the bottom. Therefore, your ratio would be 4/70 = 7/x. Cross-multiply to get 4x=490 and x = 122.5 minutes. Change that to hours if you'd like by dividing by 60!
