1. 30% of what number is 14.1? 2. Convert the given amount to the given unit. Use the fact that 1 in. = (the curvy equal sign) 2.54 cm. 81 cm; inches 81 cm =(Curvy equal sign) (Round to the nearest hundredth as needed) Thanks a bunch :)
+130515 1. 30% = .30 in decimal form
"Of" means multiply
"What Number" is "x"
"Is" means "Equal To"
So we have
.30 * x = 14.1 divide both sides by .30
x = 47 and that's the "What Number"
2. I assume you want to convert 81 cm to inches......so we have
81cm * (1 inch/2.54cm) = about 31.89 in. .....notice that the "cm" "cancel" abd we're left with the desired unit (inches)
