Question

express each ratio as a percent 13:8​

Answer 1

Answer:

5) 10% 0f 60 + 20% 0f 200 = 10/100×60 + 20/100×200 =6 + 40 = 46

6) -71-9=-80 , two rational numbers equivalent to -80 = -160/2 and -240/3

7)-8/22 - 5/11                                              LCM = 22

= -8/22 - 10/22 = -8-10/22 = -18/22 = -9/11

8)0.75 = 75/100 or 75×10^-2

9) (8/27) = (2×2×2/3×3×3) = 2³/3³ = (2/3)³

10) 13:25 into percentage ,

13/25% = 13/25 ×100 = 52%

11) Draw a number line , divide the space between 0 and 1 into 5 equal parts,

mark the point denoting the end of fourth part as 4/5

12) three rational numbers between 4/19 and 1/19

4/19 = 8/38 ,  1/19 = 2/38

rational numbers between 4/19 and 1/19 = 2/19, 3/19, 5/38

13) 5.2+16.05+26.305-1.235 =46.325

14) p/q= x% + -4%

 p/q = x-4/100

p= x-4       q=100
