Florence Belle Duncan, 62, a retired D.C. adult education teacher who specialized in home economics and consumer affairs, died of cancer Friday at Providence Hospital.

After moving to Washington about 1950, Mrs. Duncan worked for several years as a consumer educator for the Carnation Co.

In the late 1950s and early 1960s she hosted two television food preparation shows here. The first, initiated in 1957 on WTTG-TV, featured budget menus and was called "Let's Eat." The second program, which also featured a local jazz artist, was broadcast on Saturday nights on WMAL-TV, now WJLA-TV.

Mrs Duncan also organized and served as chief demonstrator for a cooking school sponsored by the Afro-American newspaper company.

In the 1960s and 1970s she taught home management, home economics and consumer education to parents and homemakers in public housing and in settlement houses as part of a D.C. government-sponsored program.

Mrs. Duncan also supervised a federally funded D.C. pilot project for welfare mothers, which was instrumental in the development of a national program.

She was the author of "Cook Book of Favorite Recipes" and coauthor of a textbook on homemaking.

Mrs. Duncan was born in Fort Valley, Ga., and reared in Detroit. She earned a bachelor's degree from St. Augustine's College in Raleigh, N.C., and did postgraduate work at Michigan State University, Wayne State University in Detroit and Howard University here.

She was a board member of the Southeast Neighborhood House and a member of the American Federation of Radio and Television Artists (AFTRA), the Adult Education Association, the National Association for Public Continuing and Adult Education, the NAACP, the National Urban League and the YWCA.

Mrs. Duncan received several awards for her work in the community.

Survivors include her husband, J. Lawrence Duncan, of Washington, a retired director of field operations for the old Department of Health, Education and Welfare.
