Answer:
(a) [tex]\frac{59}{4}[/tex] added to 21/4 gives 20.
(b) 1+0.300+6/1000 = 1.306
(c) The smallest possible decimal number up to 3 decimal places is 0.001
(d) 28/8 = 3.5
(e) 2/3 of 75 books = 50 books
1) In proper fractions, the numerator is always less than the denominator.
Step-by-step explanation:
(a) Let x+[tex]\frac{21}{4}[/tex] = 20
⇒ x = 20-[tex]\frac{21}{4}[/tex] = [tex]\frac{80-21}{4}[/tex]
⇒ x = [tex]\frac{59}{4}[/tex]
(b) Let 1+x+[tex]\frac{6}{1000}[/tex] = 1.306
⇒ 1+x+0.006 = 1.306
⇒ x+1.006 = 1.306
⇒ x = 1.306-1.006
⇒ x = 0.300
(c) The smallest possible decimal number up to 3 decimal places is [tex]\frac{1}{1000}[/tex] = 0.001.
(e) 2/3 of 75 books = [tex]\frac{2}{3}*75[/tex] = 2×25 = 50 books.
