Jamie says the value of 1.43 × (− 18/35) is close to −0.75. student a says this estimate is reasonable because the product is negative and about half of 1.5. student b says you could find the product using a calculator as follows: "divide −18 by 35, multiply the quotient by 1.43, then round the product to the nearest hundredth." does student b's approach to find the product justify the claim that jamie's estimate is reasonable?
