Final answer:
To estimate the quotient of 7/8 ÷ 5/9, round the fractions to compatible numbers, such as 1. The estimated quotient is 1.
Step-by-step explanation:
To estimate the quotient of 7/8 ÷ 5/9 using compatible numbers, we can round the given fractions to the nearest whole number or decimal. For simplicity, let's round both fractions to 1. So, we have 1 ÷ 1, which equals 1. Therefore, the estimated quotient is 1.
