In a ratio, the ratio of the two ratios is equal to 8, and the two inner terms are 5 and 12 respectively. This ratio is () or () The car can reach the destination in 7 hours at the speed of 60 kilometers per hour, and it can reach the destination in 5 hours at the speed of () kilometers per hour (1) The distance of the car is () (2) The product of two times () and () is certain, that is to say () and () are in inverse proportion 3 / 2: 3 = 2 / 3: n (m, n are not 0), then M: n = () 3 / 2: M = 2 / 3: n (M and N are not 0), then M: n = ().

In a ratio, the ratio of the two ratios is equal to 8, and the two internal terms are 5 and 12 respectively. This ratio is (40:5 = 12:1.5) or (96:12 = 5:5 / 8)
When the car runs at the speed of 60 km / h (V), it can reach the destination in 7 hours. If it wants to reach the destination in 5 hours, it can travel (60 * 7 △ 5 = 84) km / h. time (T)
(1) The distance of the car is (420 km)
(2) The product of (V) and (T) is certain, that is to say, (V) and (T) are inversely proportional
3 / 2: M = 2 / 3: n (m, n are not 0), then M: n = (9 / 4)

In a proportion, the ratio of the two ratios is equal to 5. The two internal terms of the proportion are 3 and 4 respectively. The proportion may be () or ()
Determinant

The ratio may be (20:4 = 3:0.6) or (15:3: = 4:0.8)

In a formula, the ratio of the two ratios is equal to 5. The internal terms of the ratio are 1.5 and 1 respectively. The ratio should be () or ()

In a formula, the ratio of the two ratios is equal to 5. The internal terms of the ratio are 1.5 and 1 respectively. The ratio should be (7.5:1.5 = 1:0.2) or (5:1 = 1.5:0.3)
