Jace estimated the product of 34 point 5 7 times negative 0 point 7 4 by rounding each number to the nearest tenth. What was Jace’s estimate?

Round 34.57 to the nearest tenth: it becomes 34.6. Round −0.74 to the nearest tenth: it becomes −0.7. Then multiply 34.6 × (−0.7) = −24.22, so Jace’s estimate is negative 24.22.
