​

Answer 1

Answer:

(a) $\frac{59}{4}$ 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+$\frac{21}{4}$ = 20

⇒ x = 20-$\frac{21}{4}$ = $\frac{80-21}{4}$

⇒ x = $\frac{59}{4}$

(b) Let 1+x+$\frac{6}{1000}$ = 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 $\frac{1}{1000}$ = 0.001.

(e) 2/3 of 75 books = $\frac{2}{3}*75$ = 2×25 = 50 books.
