25 is 5 more than 20 which is 25% more since 5/20 = 1/4 = 25%
To check (1.25 * 20 = 25)
Answer:
b
Step-by-step explanation:
Answer:
1. N4 = a
2. N8.25 = b
Step-by-step explanation:
1000 litre =N3
Each additional 100 litres = 5 k
100 litres
2000 litres
100 litres =5k
2000 litres = x
100x =5×2000
100x =10,000
Divide both sides of the equation by 100
x = 100k
100 Kobo = N1
x =N1
N3+N1 =N4
2. First ten words cost N6
Each additional word cost 45 k
1= 45k
5=x
x = 5×45
= 225 Kobo
100 Kobo = 1 Naira
225 Kobo = x
x = N2.25
N6 + N2.25
x = N8.25 = B
YES!!! 2.78778777 is an irrational number because it has endless numbers, and a irrational number cant be put as a fraction but rational numbers can be put as a fractio!!
