Estimate the product of 2.28 × 5.59 using compatible numbers.

Ierofanga [76]

The quotient of 2.28 × 5.59 using compatible numbers is approximately 12.75

<h3>What are products?</h3>

Quotients are result derived from the multiplication of two rational or integers. Given the expression

2.28 × 5.59

Convert to fraction

2.28 × 5.59 = 228/100 ÷ 559/100
2.28 × 5.59= 127452/10000

2.28 × 5.59= 12.75

Hence the quotient of 2.28 × 5.59 using compatible numbers is approximately 12.75
