1) 4/(1/5)
=4 ÷ 1/5
to divide fractions, multiply by the reciprocal/inverse of 1/5
=4 * 5/1
=20
4) (7/9)/7
=7/9 ÷ 7
to divide fractions, multiply by the reciprocal/inverse of 7
=7/9 * 1/7
multiply numerators; multiply denominators
=(7*1)/(9*7)
=7/63
simplify by 7
=1/9
7) (9/10)/6
= 9/10 ÷ 6
to divide fractions, multiply by the reciprocal/inverse of 6
= 9/10 * 1/6
multiply numerators; multiply denominators
= (9*1)/(10*6)
= 9/60
simplify by 3
= 3/20
ANSWER: 1) 20; 4) 1/9; 7) 3/20
Hope this helps! :)

Answer:
Step-by-step explanation:
Given is a steam and leaf plot.
This shows the age of customers who were interviewed in a survey by a store.
From the plot we can say that 10th digit is represented by the stem
For greater than 32, obviously 1,2 stem valus will not work.
For stem 3, we can leave 30 and 31 start with 2 in leaf and 3 n stem
We have 32, onwards 7 persons
Similarly for 4, we have 6, for 5 we have 5, for 6 we have 4 and for 7 we have 1
Total number of customers who have ages more than 32 years = 21
