Daja is packing her backpack for school. Her textbook weighs 1 ¼ pounds. Her notebooks weigh ¼ pound. Her other supplies weigh ¾ pounds. How much do the contents of Daja’s backpack weigh?

[I Put the fractions in to decimals!!]

2 ¼

Expansion: You would do 1.25+.25+ .75 and that would equal 2.25 OR 2 ¼

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
