Calculate the total weight of 5 bags of grain (14 kg 250 g each) and the remaining oil (initial 13 L 650 mL, used 7 L 750 mL)?

Here are the solutions to the problems: Question 6: a) Weight of 5 bags of grain Step 1: Convert the weight of one bag to grams. 1 kg = 1000 g Weight of one bag = 14 kg 250 g = (14 × 1000) g + 250 g = 14000 g + 250 g = 14250 g Step 2: Calculate the total weight of 5 bags. Total weight = 14250 g × 5 = 71250 g Step 3: Convert the total weight back to kilograms and grams. 71250 g = 71000 g + 250 g = 71 kg 250 g The total weight of 5 bags is 71 kg 250 g. b) Remaining oil in the box Step 1: Convert the initial amount of oil to milliliters. 1 L = 1000 mL Initial oil = 13 L 650 mL = (13 × 1000) mL + 650 mL = 13000 mL + 650 mL = 13650 mL Step 2: Convert the amount of oil used to milliliters. Oil used = 7 L 750 mL = (7 × 1000) mL + 750 mL = 7000 mL + 750 mL = 7750 mL Step 3: Subtract the used oil from the initial oil to find the remaining amount. Remaining oil = 13650 mL - 7750 mL = 5900 mL Step 4: Convert the remaining oil back to liters and milliliters. 5900 mL = 5000 mL + 900 mL = 5 L 900 mL The remaining oil in the box is 5 L 900 mL. Question 7: a) Place value of the digit 8 after the decimal point in 48.84 Step 1: Identify the position of the digit 8 after the decimal point. In the number 48.84, the first digit 8 is in the ones place. The second digit 8, which is after the decimal point, is in the tenths place. Step 2: Determine the place value. The place value of the digit 8 in the tenths position is 0.8 or (8)/(10). The place value is 8 tenths.
