WELCOME TO CAHSEE Week 6 NOTES- any slide with a green title should be written down in your notebook. Lesson #11Number Sense 1.2 and 1.3 Integers (15 mins) • Integers- same signs add and keep. Different signs subtract, and keep the sign of the higher number. -3 + -5= -8 -3 + 5= 2 fractions • Fractions- (adding/ subtracting) if the denominators are the same add/ subtract numerators and keep the denominators. ¼ + ¾ = 4/4= 1 ¾-¼ = 2/4= 1/2 fractions • Fractions- (multiplying/ dividing) multiply numerators, then denominators and reduce. To divide, reciprocal of second fraction and multiply. ¼ x ¾ = 3/ 16 ¼÷¾ = ¼ x 4/3= 4/12= 1/3 decimals • Decimals- add/ subtract (line up the decimals). Multiply/ divide (line up the digits) 234.0 + 5.3 239.3 234 x 5.3 1240.2 Fractions to decimals to percents • Divide the numerator by the denominator 3 4 = 4 3 = 0.75 Bootcamp Practice (15 mins) Pages 23 and 26 you may NOT write on.
