Answer:
1) 7/5
2) 9/8
3) 1/9
4) 13/5 which becomes 5/13
5) 27/8 which becomes 8/27
Step-by-step explanation:
→ The reciprocal of a number is just the 'flipped version' of it, the numerator becomes the denominator and the denominator becomes the numerator
1.
558 can be rounded to 600.
44 can be rounded to 40.
600 x 40 = 24,000
2.
9 x 802 = 9 (800 +2) =7200 + 18 = 7218
3.
3699 x 7 = (3700-1) x 7 = 25,900 - 7 = 25,893
4.
34 x 93 = 34 x (100-7) = 3400 - 238 = 3162
5.
678 x 87 = 58,986

28 is 4 times 7, so we will rewrite it like that.

7 is 7 times 7, so we will rewrite it like that.

So the simplest form is,
It will be 451.6 because 5 is tents place 68 is big number so u add 1 + 5 = 6
Answer 451.6
