Whats the upper bound for estimate for 354 + 267?

1 answer:

7 0

Personally I'd replace 354 with 360 and 267 with 270, and then add 360 and 270, obtaining 630. Similarly, estimate 63.75 + 3.63 by adding 60 and 3: 63. There's no single answer for either problem. For "upper bound," I round the given addends upward; for "lower bound," I found the addends down.

$\\ \sf\longmapsto XY+YZ=XZ$

$\\ \sf\longmapsto 7a+5a=6a+24$

$\\ \sf\longmapsto 12a=6a+24$

$\\ \sf\longmapsto 12a-6a=24$

$\\ \sf\longmapsto 6a=24$

$\\ \sf\longmapsto a=\dfrac{24}{6}$

$\\ \sf\longmapsto a=5$

YZ=5a=5(5)=25
