How to calculate 328-76 + 24?
328-76+24=326+2-76+24=326-76+2+24
Divide 328 into the form of 326 + 2, and then use the commutative law
(1) If you've learned negative numbers, it's easier to do the following:
The original formula = 326-76 + (2 + 24) = 326-76 + 26 = 326-50 = 276;
(2) If you haven't learned negative numbers, calculate them directly
The original formula is 326-76 + (2 + 24) = 326-76 + 26 = 250 + 26 = 276

- 19. Practical questions (30 19:1:19) Mechanical processing needs lubrication to reduce friction. An enterprise needs to process 90kg lubricating oil for a large-scale mechanical equipment, and the reuse rate of lubricating oil is 60%. According to this calculation, the actual oil consumption of processing a large-scale mechanical equipment is 36kg. In order to build a conservation oriented society and reduce oil consumption, a workshop of the enterprise organized personnel to tackle key problems to reduce the actual oil consumption, It not only reduces the lubricating oil consumption, but also improves the reuse rate of lubricating oil. It is found that on the basis of technological innovation, the reuse rate of lubricating oil consumption will increase by 1.6% for every 1kg reduction in lubricating oil consumption. In this way, the actual oil consumption of processing a large mechanical equipment will decrease to 12kg, How many kilos of lubricating oil is used for processing a large mechanical equipment? What is the reuse rate of lubricating oil?
